MOTOR-CARRIAG E.

SPECIFICATION forming part of Letters Patent No. 641,404, dated January16, 1900. I Application filed November 4, 1899- Serial No. 735,830- (Nomodel.)

To aZZ whom it may concern;

Be it known that 1, WILLIAM E. PEARSON, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement in Motor-Carriages, of which the following, taken inconnection with the accompanying drawings,is a specification.

My invention relates to a method of supporting and staying the severalparts of a motor-carriage and its motor; and it consists in mechanismfor supporting and staying the motor and carriage in such a manner thatthe vibration of the motor will not be communicated to the carriage-thatis, the motor and the carriage will be comparatively independent of eachother so far as shocks and vibrations are concerned.

The mechanism in which my invention is involved is illustrated in theaccompanying drawings, in which Figure 1 is a plan view showing theparts as they would appear if the body of the carriage were removed.Fig. 2 isalongitudinal section taken through the center. Fig. 3 is adetail illustrating the manner of supporting the rear end of thecarriage.

In the drawings I have indicated the carriage-body by H. I do notconfine myself to any particular style or kind of carriage, as myimprovements will apply to any kind of vehicle equally as well. Thiscarriage-body has a strong frame the end sills of which are indi-' catedby K and K, and it is supported at its front end by angle-iron straps orbrackets N N and the spring S. The rear end of the carriage-body issupported by angle-irons L L, which connect with the top of the springsS S. The said springs are attached to the rear axle'B.

The running-gear and its frame may be described as follows: The frontaxle A is fixed rigidly to the frame and does not rotate on its axis norswivel in relation to the carriagebody. Its wheels A A are connected tothe axle by short journals, which are connected to the ends of the axleA by joints A A in the usual manner. The rear axle B is rigidly attachedto its wheels B B, so as to rotate with them. The front and rear axlesare connected by rods or tubes 0 O. The said rods are connected to thefront axle by T-joints O O and to the rear axle B by T-joints G 0 Thesaid rear axle B turns freely in the joints (i 0 Inclined braces C Oconnect with and brace the rods 0 O. From the above it is seen that thefront and rear axles, the rods 0 O, and braces C 0 make together arunning-gear frame that is not directly connected with the body of thecarriage nor directly connected with the base-plate or engine-frame, aswill be explained.

The base-plate that the engine or motor is built upon is represented byE E and is supported by rods or tubes F F and F F. The ends F F of theserods are connected to the front axle A by hinged joints F F and the endsF F to the rear sill K of the body of the carriage by swinging links FF, that are suspended from the said sill, as shown in Fig. 2, thuspreventing the vibrations of the engine and its bed-plate from beingcommunicated to the carriage-body. By thus supporting the engine upon abed-plate that is pivotally hung to the forward axle by the joints F Fand to the rear sill of the body of the carriage by swinging links F F,I practically insulate the engine from the body of the carriage so faras vibration is concerned and yet have a good and strong kinematicconnection between the engine and the runninggear. I

The front of the body of the carriage is connected indirectly to therear axle B by means of rods P P. The forward ends of these rods P P areconnected to the front sill K by pivotjoints P P, and the rear ends areconnected to the axle-frame rods 0 O (and by them to the rear axle) bythe pivot-joints P P In case it is desirable to place the engine ormotor at the rear end of the carriage then the rods F F F F should havetheir front ends connected by swinging links, like F to the front sillsK and their rear ends to the rear axle B by pivot-joints, like F Motionis communicated from the engine to the shaft E and sprocket-wheel E andthence by the sprocketchain B sprocket-wheel B and rear axle B to thetraction-wheels B B.

I claim 1. In a motor-carriage an actuatin -motor supported upon a framedetached from the body of the carriage, one end of said frame beingattached to one axle of the carriage by a hingedjoint, the other endbeing attached to the swinging links suspended from one end of the bodyof the carriage substantially as and for the purpose set forth.

2. In a motor-carriage, a rigid runninggear frame, consisting of thefront and. rear axles, side rods (as O G) and inclined braces connectingsaid side rods with one of the axles; a motor-supporting frame, detachedfrom the body of the carriage, one end of said frame being attached toone axle of the carriage by a hinged joint, and the other end
